homedepot DIY garage build kit

[treesner]

Anyone ever do one of these kits? wonder if it saves much time/money over / good quality what are your thoughts?
Can anyone estimate how much permitting (California), slab, electric, insulation, paint would end up with one of these builds?

The link said that building is $35K, for the other things you mentioned, I would estimate $12-15K extra.  Slab would be $6-8K, electric $1K, permits $500 to $800, insulation $2500 to $4000 (fiberglass vs spray foam), painting I have no idea.

I think this is spot on for the most part..  The numbers will change depending on where you live but, it's the "not included" costs that can bite you in the back side.

I'm currently bidding out a 16' by 16' storage building and the differences are astronomical!  Current low bidder is at about 11k and the high bidder is at 21k..  My point being, look to your local community and get some bids for building in the size and shape that you want.  Then, compare those to the options like the one listed above..

Sounds high to me, for just the frame, and skin, and I would expect they would just use the cheapest of everything.   I'm no expert on building costs, and estimates though.  I built new buildings (high end (for their own time)waterfront houses) for a living for 33 years, but never figured any kind of estimate.

My method, from the start, for figuring out what it cost to build something, was to build it.

The only thing I know for sure is that if you furnish all the labor, along with a couple of low level helpers, you can build such for a little less than half of what it will be worth.  That was my method of pricing.  I'd know what I had in it, double that, and round up to the nearest round whatever-thousand, or ten thousand, not including the land cost, which would be on top of that.  I think that would work figuring what costs are for building any new building in your area.  My prices may have been a little low, because I never held one for longer than two weeks after I put a price on it, and I never haggled.  They were very good quality though.

The building kits I've seen from HD seem to be pretty minimal. Check local building codes to be sure they meet requirements for the intended use.

Or go to HD and find a dozen acceptable 2x studs from a bundle and your pickin and not them. 

[Tom King]

That's what I would do.  We picked every piece, and framing lumber was better then than it is now.

When I built my shop I started with a kit like that but buy the time I was done upgrading things I decided it was cheaper to make my own list and buy it that way. The numbers @Woodenskye posted look very realistic to me as well. I built mine about 15 years ago, 26x36 with a 10x14’ room upstairs, for right around $32k that included subbed out slab, heat, central air, and one day crane rental to place the roof trusses, I did the rest.

[duckkisser]

cost almost as much as my house

I often find HD's web site entertaining.  I followed @treesner's link to have a look at the kit and, scrolling down the page a bit, found the "Frequently Bought Together" section.  It lists this kit ($34,499), a kit for a 48'x60' garage ($41,999) and a kit for a 44'x40' garage ($39,999).  "Price for all three: $116,497."  Yeah - I'll bet somebody places an order for that combination every couple of days.  Maybe they have a lot of customers like my wife - she orders three sweaters, decides which one she likes best, and sends the other two back.

$1k for electrical?  I got quoted $2500 for a sub panel install here in KC.  Gotta think wiring up a new building would be significantly more, especially in California.

You may be right, a lot of unanswered questions, is the OP able to do the wiring himself, new service, upgrade existing, or just running from the house to a sub panel.  My quote was based on my experience with my electrician running from main house panel to new sub panel 100 feet.

$1000 for electrical would get you a minimal amount of receptacles, switches and light outlets, but no panel of incoming feeder. No where near enough for use as a shop. Assuming a 100A feeder to the house 50' away, panel for the building, and a decent amount of electrical for receptacles & lighting would be closer to $4000 - $6000.

Here are some budget numbers from my shop quote in 2015. My shop is 30 x 34 so it is close, in size, to what you are looking at. Some of these numbers changed because we added or deleted during the building process. Also building materials and labor fluctuate and vary by region and contractor. 

Framing material $9,300:  roof scissor trusses, floor joists, LVL beams, sheathing, subfloors, 2x6 wall studs etc. This is just the start and it is worth saying that it was advantech subfloor and the green sheathing done with zip tape. I think some of this is higher quality than the HD package. I'm guessing my subfloor cost roughly the same as the attic floor in the HD plan. Close enough for a rough comparison.

Doors and windows $3,700. Again these are pretty high quality. I have 4 slider windows that are 4ft by 8ft. Two 2 x 4 ft gable fixed windows and two double entry doors. Outswing for the main shop and the normal inswing for the basement. No garage doors.

Excluding the foundation I have $13k for the building shell. 

To compare to the HD package add these two subcontractor jobs

  Roofer $4,350.00 (shingles and installaiton)
  Siding mat. & labor $ 6,725.00 (vinyl to match house - HOA requirement)

That is another $11k installed bringing it up to just over $24,000. Labor to get it dried in was about $7,500. By my calculations my builder gave me a building shell comparable to the HD package for less than HD is charging for the kit. 

Here are the remaining major items that I put into my shop. You are going to want insulation even if you don't install heat or air. I also highly recommend a sink. My wife has 216 sq ft for stained glass studio and water was a must. If you have a sink you might as well add a toilet. In my mind these are a must for a stand alone building. I added a shower for those days when I get really dirty in the yard or shop. Not really a must but if you do then hot water is a must. If I did it again I might delete the shower and get one of those little 10 gallon undersink hot water heaters. It's still nice to have hot water to wash up, clean brushes, etc. I'm just saying you can skimp where you want and spend more on what's important.

Other subcontractors:
  Insulation $ 2,280.00  (I have a basement, wood floor is insulated underneath. This included all exterior walls, ceiling, and floor to residential code.) 

 Downspouts $620.00
  Gutter Helmet $ 1,040.00
  Plumbing $ 3,500.00  (full bath and a utility sink. Includes labor and materials to tie into house plumbing and s eptic tank.)
  Drywall mat. And labor $ 6,928.00 (The shop has a spouse hobby room, bath room, storage closet, and vaulted ceiling. I finished everything with drywall and paint.)
  Electrician $ 5,940.00 (A 200A panel with 17 circuits. 220v Mini-split, hot water, table saw, dust collector, bandsaw. 3 110v circuits for the wood shop, one for the bath, one for the wife's room, lights, outside GFI, basement GFI. I just counted the 110v outlets in the wood shop - 20 wall outlets, 3 ceiling, and 2 in the floor. I don't have a spot that is more than 4 feet without an outlet and I wish I had more. I also have the 220v in the floor for the TS and BS)
  Heating and Air $6,893.00 (I can't remember if this is accurate. We went with a minisplit with two indoor units. )

Okay. This got way long but I hope it gives you some help to see a real world case. These were my budget numbers but most of it came close in the end except where we changed things.
